COPD sufferers have poor quality sleep, study finds

Chronic obstructive pulmonary disease (COPD) affects a
person's ability to have good sleep.

Researchers at the Department of Respiratory and Sleep Medicine at
St Vincent's University Hospital in Ireland found that COPD
sufferers experienced poorer sleep quality in bed than others who are of a similar age,
but do not have the condition.

Professor Walter McNicholas said patients with COPD reported
suffering from issues such as fatigue, sleepiness and impaired
quality of life.

"The study ... showed that such patients experience poor sleep
quality, which may contribute to these debilitating symptoms,"
Professor McNicholas added.

He stated the findings, which appear in the journal Respirology,
show there is an association between daytime hypoxemia and sleep
efficiency.

However, he believes further research needs to be carried out into
the topic to properly understand the relationship.

COPD - a name for a collection of lung diseases - is thought to be
ranked fifth in the burden of diseases worldwide.
